4 Principles
Decompose the sample with hydrochloric acid, hydrofluoric acid and perchloric acid, evaporate to nearly dryness, dissolve the salts with hydrochloric acid, and dilute to constant volume: in atomic absorption spectrometer
Above, an air-acetylene flame was used to measure the absorbance of potassium and sodium at wavelengths of 766:5nm and 589:0nm respectively, and the calibration curve method was used to analyze
Don't calculate the mass fraction of potassium and sodium:
